EcoFlow DELTA 3 Plus

The DELTA 3 Plus is a higher-capacity variant in EcoFlow's third-generation DELTA lineup, offering expanded watt-hour storage and faster recharge rates than both the DELTA 2 and the base DELTA 3. Exact capacity and output specifications are listed in EcoFlow's current product documentation, as the DELTA series has undergone multiple generational updates.

EcoFlow's DELTA-series power stations are commonly used for CPAP machines, and the DELTA 3 Plus's expanded capacity makes it well-suited for overnight CPAP use during camping or power outages. Runtime depends on the specific CPAP model's power draw and whether heated humidification is enabled.

EcoFlow transitioned to LiFePO4 (lithium iron phosphate) battery cells starting with the DELTA 2, and the third-generation DELTA lineup continues this chemistry. LiFePO4 provides longer cycle life—typically rated for 3,000+ cycles to 80% capacity—compared to the older NMC cells used in the original DELTA.

The Anker SOLIX F2000 offers 2,048Wh of capacity and 2,400W of AC output, positioning it as a direct competitor to EcoFlow's DELTA-series flagship models. The DELTA 3 Plus aims to differentiate through EcoFlow's faster recharge technology and its ecosystem of expandable battery options.
